Mailbutler vs Missive

Mailbutler

• People who want tracking and templates inside Apple Mail, Gmail or Outlook
• Teams sharing an info@ or sales@ inbox without moving to a new mail app
• Mixed teams whose members use different email clients

Missive

• Small teams sharing addresses such as support@ or sales@
• Teams that want to discuss emails internally instead of forwarding them
• Businesses that also talk to customers over SMS, WhatsApp or live chat

Mailbutler

• It is an add-on, not a mail client: it runs inside Apple Mail, Gmail in Chrome, Safari or Edge, and Outlook. The iOS and Android apps are companions that need a desktop install.
• The free Starter plan puts a visible Mailbutler watermark on sent emails and covers only basic tracking and signatures.
• The AI Smart Assistant, per-recipient tracking and full open history need the Smart plan at $11 per user / month, billed yearly.
• HubSpot and Salesforce tracking sync, a custom tracking subdomain and IP exclusion are limited to Business. Custom SMTP is listed as coming soon.

Missive

• There is no free plan; once the 30-day trial ends a paid plan is required.
• Starter is limited to 5 users and leaves out integrations, rules, API access, the AI assistant and analytics.
• SAML single sign-on and IP restriction are only available on Business.
• Missive says it offers no discounts for students, nonprofits or schools, and yearly plans are not refundable.

Mailbutler

Email tracking

Shows when a message was first opened and its links first clicked, with real-time notifications. Full open history, device and location details and per-recipient tracking start at the Smart plan.

Templates and mail merge

Message templates with placeholders, and mail merge that fills them from Apple, Google or Outlook contacts, HubSpot, Salesforce or a CSV file. Both start at the Professional plan.

Inbox collaboration

On a shared inbox you already have, teammates can assign emails, see who is viewing or replying to a message, and share notes, tasks and color-coded tags.

Automations

Rules made of a trigger, optional conditions and actions can tag emails, add notes or tasks and apply signatures when a draft is created, an email is sent or opened, or a link is clicked.

Smart Assistant

The AI assistant drafts emails and replies from a few keywords, corrects and rephrases drafts, summarizes messages and finds to-dos in them. It is part of the Smart and Business plans.

Email signatures

Signature templates, custom HTML signatures, call-to-action buttons and team sharing are on every plan. UTM link personalization and dynamic content need Business.

Missive

Shared inboxes and team spaces

Team inboxes sit next to personal accounts, grouped into team spaces. Conversations can be assigned to a person or a team, with controls over who sees what.

Internal discussion in threads

Teammates talk about an email in an internal conversation attached to the thread, so nothing has to be forwarded or CC'd.

Collaborative drafting

Several people can write the same reply together in real time before it is sent.

Rules and automations

Automate repetitive handling such as assigning or tagging with up to 1,000 rules. Rules are available from the Productive plan.

Multi-channel inbox

Email from Gmail, Microsoft 365, iCloud or any IMAP account appears alongside SMS, WhatsApp, Messenger, Instagram and live chat conversations.

AI assistant and integrations

An AI assistant drafts and translates replies and can pull context from connected tools over MCP. It comes with Productive, along with 25+ app integrations and the API.
